Test principle This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with 5-Hydroxytryptamine(5-HT) protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to 5-Hydroxytryptamine(5-HT). Next,Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of 5-Hydroxytryptamine(5-HT) in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision Intra-assay Precision (Precision within an assay):CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays):CV%<10%

Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.

Recovery Matrices listed below were spiked with certain level of recombinant 5-HT and the recovery rates were calculated by comparing the measured value to the expected amount of 5-HT in samples.

Matrix Recovery range Average
serum(n=5) 80-93% 86%
EDTA plasma(n=5) 94-105% 98%
Heparin plasma(n=5) 95-107% 89%
Linearity The linearity of the kit was assayed by testing samples spiked with appropriate concentration of 5-HT and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Matrix 1:2 1:4 1:8 1:16
serum(n=5) 79-94% 87-96% 98-105% 82-93%
EDTA plasma(n=5) 95-102% 93-101% 97-105% 95-103%
Heparin plasma(n=5) 78-96% 86-92% 84-98% 89-102%
